Everything you need to know about repairing corrupted videos, rebuilding metadata, and recovering playable files with VideoRepair.
Select your corrupted video file. Optionally add a matching reference clip from the same device for stronger reconstruction results.
Our structure-aware repair engine inspects the file container, rebuilds damaged metadata, and chooses the best recovery path — all locally in your browser.
Preview first, then either unlock that repair once or use Pro for unlimited downloads when playback looks right.
Before you repair
Read how VideoRepair rebuilds missing metadata locally, where reference files help most, and what limits to expect before you upload a damaged video.
VideoRepair supports MP4, MOV, AVI, M4V, M4A, 3GP, and compatible 3G2 files. MP4, MOV, M4V, M4A, 3GP, and 3G2 repair works best when the file still contains usable H.264 video and AAC audio tracks. AVI repair currently focuses on classic AVI files with recoverable stream data.
The current in-browser file size limit is 4GB per video. Files are processed in chunks using streaming architecture, so large files can still be repaired with minimal memory usage.
All video processing happens entirely in your browser using WebAssembly technology. Your files are never uploaded to any server. The repair engine inspects the container structure, identifies broken offsets or missing metadata, and rebuilds the parts needed to make the video playable again.
Absolutely. Privacy is our top priority. All video processing is performed locally in your browser — your files never leave your device. We do not collect, store, or transmit any of your video data.
A reference file is a normal, playable video recorded by the same device and settings as the corrupted file. It helps the repair engine recover missing codec and timing details, such as resolution, frame rate, and encoding profile, when the damaged file has lost too much metadata to describe itself reliably.
You can repair and preview videos without an account. To unlock a final download, you can either buy a one-time export for a successful single-file repair or subscribe to Pro for unlimited downloads and batch repair. Creating an account also makes it easier to keep and manage your repair history.
